Impact of nanoplastics uptake on modulation of plant metabolism and stress responses: a multi-omics perspective on remediation and tolerance mechanisms
Researchers reviewed how nanoplastics accumulate in plant tissues and disrupt metabolism, finding that these particles impair nutrient uptake, trigger reactive oxygen species overproduction, and alter gene and protein expression, while multi-omics approaches are revealing the molecular stress-response networks that plants use to tolerate or remediate nanoplastic contamination.
Response of rice (Oryza sativa L.) roots to nanoplastic treatment at seedling stage
Researchers exposed rice seedlings to polystyrene nanoplastics and found that the particles were taken up by the roots, aided by water-transporting proteins in the plant. The nanoplastics triggered oxidative stress, reduced root length, and disrupted carbon metabolism and hormone production in the seedlings. The study raises concerns that nanoplastic contamination in agricultural soils could affect crop growth and potentially enter the human food supply through rice consumption.
The Oryza sativa transcriptome responds spatiotemporally to polystyrene nanoplastic stress
Researchers profiled the full transcriptome of rice roots and leaves at multiple time points during polystyrene nanoplastic exposure, finding that nanoplastics suppress photosynthesis and sugar metabolism while activating plant defense pathways — with effects differing between organs and time points in ways that suggest indirect harm via disruption of plant-microbe interactions.

Mechanistic insight into the intensification of arsenic toxicity to rice (Oryza sativa L.) by nanoplastic: Phytohormone and glutathione metabolism modulation
Nanoplastics at environmentally realistic levels did not harm rice plants on their own, but when combined with arsenic they made arsenic toxicity significantly worse, reducing plant growth by up to 23%. The nanoplastics increased arsenic uptake by disrupting plant hormones and weakening the plant's natural detoxification systems. This is concerning because rice is a staple food for billions of people, and agricultural soils increasingly contain both nanoplastics and heavy metals.
Nanoparticles as catalysts of agricultural revolution: enhancing crop tolerance to abiotic stress: a review
This review looks at how nanoparticles can help crops withstand environmental stresses like drought, salt, and heavy metal contamination.
